The Staff+ Application Security Engineer will support Anthropic’s M&A program by running application security due diligence before close and leading secure integration activities after acquisition. The role emphasizes automation, secure tooling, and clear risk communication across deal stakeholders.
Application Security for Pre-Close Due Diligence
- Lead security due diligence for prospective acquisitions, including coordinating external penetration testing and conducting threat modeling of target architectures.
- Assess security controls and produce a security risk readout for leadership ahead of close and integration planning.
Post-Close Security Integration and Remediation
- Drive post-close security integration by standing up static and dynamic analysis coverage for acquired codebases.
- Track high- and critical-severity remediation through to closure.
- Fold acquired assets into bug bounty scope and onboard repositories to Anthropic’s automated vulnerability remediation and reporting systems.
Cross-Team Deal Coordination
- Coordinate with adjacent security engineering teams including supply chain, cloud, corporate security, and detection & response for their respective integration areas.
- Partner with stakeholders across each deal, including corporate development, legal, security leadership, and engineering teams inheriting acquired systems internally, as well as engineering and security counterparts at the target company externally.
- Translate technical security workstreams so they remain clear to a range of audiences throughout the integration lifecycle.
M&A AppSec Playbook Automation
- Formalize and scale Anthropic’s M&A security playbook, including a risk-scoring model, diligence runbook, and integration checklist.
- Convert manual steps into Claude-powered tooling wherever possible.
Operational Rotation and AppSec Contributions
- Share the team’s on-run rotation for activities such as bug bounty escalations, launch consults, and incident response, with rotation coverage swapped during periods of active deal work.
- Contribute between deals to core AppSec efforts, including secure design reviews and threat modeling for agentic systems, as well as the team’s security automation roadmap.
Required Qualifications
- Hands-on application and infrastructure security experience, including cloud and containerized environments.
- Ability to rapidly assess unfamiliar codebases or architectures and produce prioritized risk assessments for non-security audiences.
- Production-quality coding experience in at least one of Python, Go, Rust, or TypeScript.
- Practical threat-modeling and vulnerability identification skills, including finding and reasoning about real bugs in real systems.
- Comfort working with high autonomy, ambiguity, and tightly held confidential context.
- Clear written and verbal communication across executive, legal, corporate development, and engineering stakeholders, including counterparts at acquired companies.
